In the field of machining, different parts of the processing complexity, need to choose different processing technology to complete. In the process of precision CNC machining, we will encounter various parts processing, some parts are complex, we need to find the appropriate processing technology, which is often said to be the best way. Let’s take a look at the methods and difficulties in the process of precision CNC machining?
The first is precision CNC machining method, which includes cutting, abrasive machining, non-traditional machining and compound machining; According to the mechanism and characteristics of machining methods, it can be divided into three categories: removal machining, combination machining and deformation machining. At present, the traditional machining methods represented by cutting, grinding and polishing still occupy the main position.
The third is the difficulty: in the process of precision CNC machining,
① Ultra micro machining is just like cutting discontinuity, so the stress is difficult to remove;
② The stiffness and thermal deformation of the process system are large, which have great influence on the machining accuracy;
③ The micro deformation of tool and workpiece surface is random,
It is difficult to control the precision
① Precision machining mechanism;
② Precision processing equipment;
③ Precision machining tools;
④ Workpiece material;
⑤ Precision measurement and error compensation technology;
⑥ Working environment, conditions, etc.
The above are the methods and difficulties in the process of precision CNC machining!, Thank you for your attention!
